Nanocomposite ablative materials for thermal shields of re-entry vehicles
Carbon-phenolic ablative heat shields represent an effective solution for the thermal protection of reentry spacecraft and they are typically composed by a porous carbon preform partially filled by phenolic resin. In this work carbon-phenolic materials modified by different amounts of ceramic nanoparticles were manufactured and investigated and the performaces of the obtained nanocomposite ablators were assessed in terms of thermal protection and ablation resistance.
